Enclose and match, when energized between t when being in t3 to t4 range, the corresponding data volume is just the first data volume.
Step S22: the time range packet between the record start time and record end time of first data volume
In the case where including the object time range, corresponding seismic data is separated from first data volume, as described specified
Big gun collection record.
In the present embodiment, the time between the record start time and record end time of first data volume
In the case that range includes the object time range, refer to that the corresponding time range of first data volume covers the mesh
The case where marking time range.Specifically, the when a length of T of the object time range then wants for example, the firing time is t
The corresponding object time range of the single-shot data of acquisition is t to t+T, when the time range of the first data volume is t1 to t2, if
The range of t1 to t2 covers the range of t to t+T, then the earthquake number of t to t+T time range is isolated from the first data volume
According to.Certainly, isolating time interval of the t into the seismic data of t+T time range between each time point can be preset,
The time interval being also possible between each time point in first data volume is identical.The duration of object time range
It can change.
Above embodiment determines the first data volume according to firing time, when the corresponding time range of the first data volume is covered

Range does not include the case where that the object time range refers to that the object time range is more than that first data volume is corresponding
Time range.Specifically, for example, a firing time t1, and record time span ts1, the record of first data volume
Finish time is ta, the case where for ts1 > ta-t1, just for the record start time of first data volume and record end when
Between between time range do not include the case where the object time range.It is corresponding, the firing time is obtained to described
The first seismic data in the time range of the record end time of one data volume is to obtain t1 to ta in first data volume
Seismic data in time range.

In the case that range does not include the object time range, there may be errors for the seismic data got.For example, described
There are in duplicate situation with second data volume for one data volume, it is understood that there may be following situations, the first seismic data are corresponding
Time range is the seismic data of 9:00:00 to 9:00:03, and the corresponding time range of the second seismic data is 9:00:02 to 9:
The seismic data of 00:05, after merging, identical seismic data portion is computed repeatedly, the corresponding time model of the seismic data after merging
It encloses for 9:00:02 to 9:00:05.And the duration of the object time range for preset firing time and setting, the target
Time range should be 9:00:00 to 9:00:06.Then at this point, there are 1 second error times.Record corresponding error message.Institute
